TUBE REPLACEMENT
Preamp Tubes 12AX7A
— No adjustment required
Output Tubes 6L6GC
— After replacing output tubes, output tubes bias voltage should be checked with Standby switch
set to On, no signal input, and all controls set to minimum. If output tube bias voltage is not correct, amplifier will sound
unusually distorted with mushy audio and output tubes may overheat. Normal output tube bias voltage should be —
52VDC on Pin 5 of all output tubes. For best results use matched output tubes.
